I second this.Hi Deino,
The 052 modules marked there actually look like the superstructure modules for the two ships already in the dock. There is definitely another 055 waiting to be moved into the dock (you can see the blocks laid out in the dock for it to sit on as well as the hull modules next to it) but I don't yet see hull modules for another 052.
The 052D in the drydock clearly lacks its topside superstructures. Meanwhile, the fact that we see topside superstructure modules for 052D at the staging area is suggestive is suggestive that it is for the 052D in the drydock.
If we had any pictures of additional 052D modules in the staging area then it would indicate there is another 052D in the works, however we don't see that.
So IMO we see "only" 4 055s and 5 052Ds in that picture.
